They may include products with different sizes or colors.\n\u003cbr\u003e*Product design and specifications are subject to change without notice. Please be aware.\n\u003cbr\u003e*When installing the S-Stage bore up kit, simultaneous installation of an injection controller is required.\n\u003cbr\u003e*Injection controllers vary depending on the vehicle model and frame number. If purchasing simultaneously, please purchase the Hyper S-Stage specifically designed for your vehicle.\n\u003cbr\u003e*Since the displacement will be 125cc or more, it is not possible to ride on public roads under a moped class 2 registration. It is for competition use only.\n\u003cbr\u003e*By installing the SP Takegawa S-Stage bore up kit, engine output and torque will significantly increase, which will increase the load on the crankshaft, such as twisting and deflection. To reduce the load on the crankshaft, SP Takegawa recommends simultaneously installing a crankshaft support adapter. The crankshaft support adapter adds support by a ball bearing to the end of the crankshaft flywheel side, thereby suppressing twisting and deflection and increasing the durability of the crankshaft.\u003c\/p\u003e","brand":"スペシャルパーツ武川(SPECIAL PARTS TAKEGAWA)","offers":[{"title":"Default Title","offer_id":47208274329835,"sku":"tk-01-05-0385","price":35716.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0689\/1021\/9499\/files\/tk-01-05-0385.jpg?v=1766738490","url":"https:\/\/bikeman.jp\/en\/products\/tk-01-05-0385","provider":"バイクマン","version":"1.0","type":"link"}
